Abstract

This endoscopic system is configured to be provided with: a light source device for irradiating an illumination light toward a subject; an image acquisition unit for capturing reflected light from the subject by an imaging element and acquiring a color image including at least three color components; and an evaluation unit that, inside a color plane defined by at least two color components of the at least three color components, works out evaluation results relating to a target disease of each pixel on the basis of an angle formed by line segments connecting a prescribed reference point set inside the color plane and points corresponding to pixels in the color plane for each pixel constituting the color image acquired by the image acquisition unit, and a reference axis correlated with the target disease. The reference axis is set so as to pass through the prescribed reference point.

Description

technical field [0001] The present invention relates to an endoscope system and an evaluation value calculation device for calculating predetermined evaluation values. Background technique [0002] In general, the lesion will show a different color from the normal mucosal tissue. In recent years, with the improvement of the performance of color endoscope devices, operators have been able to reliably diagnose lesions that are slightly different in color from normal tissues. However, in order for an operator to correctly and reliably diagnose a lesion from a normal tissue based on subtle differences in color on an image captured by an endoscope, long-term training is required under the guidance of skilled technicians. Furthermore, even a skilled operator cannot easily and reliably diagnose a lesion based on a slight difference in color, and careful work is required. [0003] Therefore, for example, Japanese Unexamined Patent Application Publication No. 2014-18332 (hereinafte...
